Natural and Adaptive Interview Test
Natural Conversation
Our AI reads not only linguistic information, such as the user’s response itself, but also nonverbal information, such as tone of voice and facial expressions, eye gaze, and head nods, to enable smooth and interactive conversations as speaking with a human.
Adaptive Interview Strategy
To elicit the learner’s ability to the full extent, our AI agent adaptively changes topics and questions depending on the user’s English proficiency. Topics range from simple daily life to complex social issues.
Assessing overall English conversation skills
LANGX Speaking uses the latest AI-based automated scoring system to quickly calculate a score for each of the six perspectives in addition to the overall evaluation. User’s overall speaking ability will be assessed on a six-point scale based on the Common European Framework of Reference for Languages, an international standard. The categories measure the following abilities.
- Range — Ability to use a wide range of expressions and complex sentences
- Accuracy — Ability to construct understandable and appropriate sentences
- Phonology — Ability to speak clearly and audibly using articulation, intonation, and rhythm
- Fluency — Ability to continue speaking at an appropriate speed, naturally and without stagnation
- Coherence — Ability to connect and talk about a variety of information, including specific examples and reasons
- Interaction — Ability to appropriately answer listeners’ questions and collaboratively develop a story
